SPECIFICATION forming part of Letters Patent No. 712,999, dated November 4, 1902.

Application filed August 28, 1900.

To @ZZ whom, it nung concern:

Beit known that I, BRUCE FORD, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia and 5 State of Pennsylvania, have invented certain new and useful Improvementsin Storage Batteries, of which the following is a specification.

The invention relates to storage-battery to plates and supports therefor.

In the present state of the art the hard-rubber frame, which is applied in sections, is probably the best exemplitication of means of support for a battery element; but this pensive.

The object of my invent-ion is to provide a battery-plate which shall be self-sustaining and which will be superior to all other types 2o in respect to the economy it affords in manufacture and its general efficiency.

The invention consists in the improved battery-plate and in the novel features of construction thereof, as will be hereinafter pointed out, and defined in the claims.

The nature, characteristic features, and scope of the invention will be readily understood from rthe following description, taken in connection with the accompanying draw- 3o ings, forming part hereof, and in which- Figure l shows a blank for a battery-plate, the dotted lines defining the strips for forming lthe bead or tubular iiange which constitutes a preferred means of carrying the invention into practice. Fig. 2 is a face View of a battery-plate provided with a bead, and Fig. 3 is a cross-section through the plate.

In the drawings, ct is abead or iiange formed by turning or folding the edges of a blank or 4o sheet of suitable material, which may be rolled metal, as lead or an alloy thereof. This beadv or lian ge a if arranged with its axis in alinement with the plane ofthe support Serial No. 28,345. (No model.)

insures even distribution of the active material or material to become active, b, on each face of the plate or support. The bead or flange imparts the requisite stiffness to the plate or support and is 'also useful as a guide in the application of the active material. It

is much cheaper than a frameiof rubber and 5o much more easily made. If desired, suitable wires, as d, may be inserted inthe flange at i the corners'of the plate, so as to strengthen them.

It will be obvious to those skilled in theart to which the invention appertains that modiiications may be made in detail Without departing from thespirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set 6o forth, and illustrated in the accompanying drawings; but,

Having thus described the nature and Objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A flat battery-platehavingitsedge turned over to form a tubular bead constituting` a support, for the active material or material to become active, substantially as described.

2. A flat battery-plate having its edges bent 7o to constitute a hollow tubular bead the axis of which lies in the plane of the plate, and which constitutes a support for the active ma terial or material to become active, substantially as described.

3. A battery-plate havingits edges bent to form a hollow tubular bead and having wires inserted in said bead, substantially as de-Y scribed.

In testimony whereof I have hereunto So signed my name.
